“…Various electrodes have been used for the electrochemical reduction of TNT, such as: glassy carbon [10], carbon-fiber [9,14,16], carbon nanotube-modified glassy carbon [18], tin-carbon [15], gold [17], gold modified with self-assembled monolayers [11], boron doped diamond [12], polycrystalline Pt [19], and copolypeptide-doped polyaniline nanofibers [20]. The state-ofthe-art in electrochemical sensing of explosives has recently been reviewed [21].…”

“…In order to recognize molecular substructures like the olfactory system, we constructed nanostructure on the sensor surface and controlled the surface affinities that are attributed to molecular substructure [9]. Designing of nanostructures is necessary to detect a substructure of molecules.…”

“…The detection limit was 7.33 10 À9 m at a signal-to-noise ration of three (S/N = 3), which is lower than some published works. [37,38] Moreover, FUN-PANI-MIP also has a much better performance than the traditional MIP-modified electrode that ranges from 8.80 10 À6 to 3. 17 10 À4 m with detection limits of 2.90 10 À6 m (S/N = 3, figure not shown).…”

This paper reports a monomer strategy for imprinting of 1,3‐dinitrobenzene (DNB) molecules at the surface of conductive functional polyaniline nanofibers (PANI) for the first time. It has been demonstrated that the vinyl functional monomer layer on the PANI surface can not only direct the selective occurrence of imprinting polymerization, but can also drive DNB templates into the polymer through charge‐transfer complexing interactions between DNB and functionalized PANI. These two basic processes lead to the formation of DNB‐imprinted polymers at the surface of polyaniline nanofibers. The capacity to uptake DNB shows that selectivity coefficient in the nanofibers polymers is nearly three times as high as that of traditional imprinted materials and the nanofibers polymers also possess high selectivity toward DNB in comparison to similar nitroaromatic compounds. A linear response of DNB concentration between 2.20×10−8 and 3.08×10−6 M was exhibited with a detection limit of 7.33×10−9 M (S/N=3). These results reported here could form the basis of a new strategy for preparing various polymer‐coating layers on polyaniline supports and the molecular imprinting techniques discussed could also find applications in the fields of separation, trace detection, and environmental monitoring.
